Hi,

I have an OPI with two menu buttons. The first menu button (mb1) allows the operator to choose between two PVs. The chosen PV is written to the INPB field of a subroutine record.

I would like the second button (mb2) to allow the operator to choose the scan rate of the PV chosen by the first button. It has the "Actions From PV" property set to "yes".  I added a rule to the second button that triggers on the subroutine INPB field and modifies the pv_name property. Here is the generated script:

importPackage(Packages.org.csstudio.opibuilder.scriptUtil); 
var pvStr0 = PVUtil.getString(pvs[0]);
if(pvStr0=="i2fci CP NMS")
	widget.setPropertyValue("pv_name","i2fci.SCAN");
else if(pvStr0=="lefc1i CP NMS")
	widget.setPropertyValue("pv_name","lefc1i.SCAN");
else
	widget.setPropertyValue("pv_name","");

When I choose a PV with mb1 I am pretty sure the rule runs since I see mb2 become disconnected briefly and then if I right click mb2 and show PV info I see the PV selected by mb1. However changing the scan rate using mb2 always changes the scan rate of whatever PV was originally chosen (in the subroutine INPB field) when the OPI started.

Is this the expected behaviour?

Thanks,
Damien
